Insight 64bit windows version

[Roland Schwingel <roland at onevision dot com>]

Hi...

Has anyone already tried that too? Any experiences?

Since a few days I am trying to build an insight (based on gdb 7,4) for 
windows 64bit using mingw-w64 compilers.
I got already quite far, but not far enough.

I got a big problem in the beginning with the intree tcl/tk/itcl/itk 8.4 
based versions. They are IMHO way to old to work on 64bit windows. I 
looked at tcl 8.5 which is already way better in regard of win64bit but 
still not as good as win64 friendly as tcl/tk 8.6beta.

So I updated my system to the current tcl/tk 8.6 source from the tcl/tk 
repos. When running tk's 64bit wish on windows 7 64 I can run the tk 
supplied tests just fine. I upgraded itcl/itk also to the most recent 
versions (4.0beta) to match the tcl/tk versions. I am using iwidgets 4.0.2.

I also had to give some love to libgui in regard of windows 64bit. It 
hasn't got any attention for around a decade so it just refused to build 
for win64.

So I can link insight now. For regressions reasons I am also compiling 
insight for windows 32 bit and linux 32 bit from the very same source 
with the very same compilers and the very same settings. On all 
platforms I do get the very same result. Insight bails out with some tcl 
errors on startup. I am just starting out to learn tcl to get insight 
going but maybe someone can give me a hint whats going wrong here. My 
tcl knowledge is still VERY MUCH limited.

Error message appearing in a window:

invalid command name "::.srcwin0.srcwin"
invalid command name "::.srcwin0.srcwin"
    while executing
"::.srcwin0.srcwin sizeWinByChild toolbar"
    ("after" script)

When setting GDBTK_DEBUG to 1 my insight writtes an insight.log. I have 
cutted out the relevant pieces:

When I am unwrapping the one big error in the middle It looks like this:

_build_win returned: can't use empty string as operand of "!"
    while executing
    "if {!$Tracing}
    {
    # In source-only mode, disable these buttons.  Otherwise, enable
    # them.

        tset state..."
        (object "::.srcwin0.srcwin.container.pane0.childsite.con" 
method "::SrcBar::_set_stepi" body line 4)
        invoked from within
        "_set_stepi"
        (error in configuration of public variable "::SrcBar::displaymode")
        (while configuring option "-displaymode" for widget

        invoked from within
        "::itcl::builtin::Archetype itk_initialize {*}$args"
        (object "::.srcwin0.srcwin.container.pane0.childsite.con" 
method "::itk::Archetype::itk_initialize" body line 2)
        invoked from within
        "itk_initialize -updatecommand {::.srcwin0.srcwin 
toggle_updates} -updatevalue 1"
        ("eval" body line 1)
        invoked from within
        "eval itk_initialize $args"
        while constructing object 
"::.srcwin0.srcwin.container.pane0.childsite.con" in 
::SrcBar::constructor (body line 34)
        invoked from within
        "SrcBar $_toolbar $this  -updatecommand [list $this 
toggle_updates]  -updatevalue $do_updates"
        (object "::.srcwin0.srcwin" method "::SrcWin::_build_win" body 
line 6)
        invoked from within
        "_build_win"

The error at the end is the same as presented in the alert panel and 
maybe results from the first error.

The plain commandline gdb generated with my setup appears to work 
without problems on all platforms, so I believe the problems comes from 
somewhere iwidgets/itcl/itk/gdbtk tcl code not from C code. It also not 
a win64 only problem as I have it on win32 and linux, too. I think there 
must be something (hopefully small) which needs to be changed in the tcl 
parts of insight/iwidgets.

Any help is very much appreciated,

Roland
